Changes in impersonation.mdx

Background: I was following along the tutorial and noticed issues. I had made changes that fixed them. Works for me.

Fixes ImpersonatingUserNotice.tsx because return null can cause a Suspense to never finish loading.
Fix some imports that were not used or from the wrong location. In particular, queryClient was global and no import was needed. And useMutation import seems to be moved to /auth.
Casting as Role to remove type mismatch warning.

My package.json is vanilia, from blitz new.
